Arabic adaptation and validation of the revised amyotrophic lateral sclerosis functional rating scale (ALSFRS-R): Egyptian study.

ALSFRS-R is 12-item scale used to assess disability and to measure disease progression in ALS patients. The objective is to validate the Arabic version of ALSFRS-R based on the original English version. This is a cross sectional study. ALSFRS-R was administered to 162 Egyptian patients with ALS after being translated in Arabic, and reapplied after 1 week. Patients were recruited from 2 centers: Neuromuscular unit, Ain Shams University hospitals and the specialized ALS clinic which is located at the international medical center (IMC). No significant differences were found between the application and reapplication of the scale ( = 0.5). The linear regression and internal consistency that were measured by Pearson correlation and alpha Conbrach respectively were significant. The Arabic version of the ALSFRS-R proposed by the current was proven to be reproducible and valid among Egyptian ALS patients. Thus, it will provide a useful tool for professionals to evaluate Arabic speaking patients in clinical practice and research.
